I would have expected GL acceleration as well. Did you find a statement that only X was going to be accelerated ?

I didn't say "only X". I initially thought the article was about "accelerated SI drivers" in general,
but realized it was specifically about leveraging the existing work through glamor to benefit X from it as well.
Or did I miss something again?

AFAIK most distros (perhaps all) have only been enabling KMS support for SI, along with the shadowfb-based "modesetting" X driver (no HW acceleration) and a software-rendering GL driver (ditto).

The point of the article AFAIK is that F19 will be enabling both X (via Glamor) and GL acceleration by default. The potentially confusing thing is that Jerome's specific request related only to the addition of Glamor, presumably since Mesa is already part of Fedora while the article talked about accelerating both X and GL.

The reason that GL doesn't get accelerated without X acceleration is that putting the frame buffer in GPU memory (to make GL acceleration fast) has the unfortunate side effect of making software-rendered X really slow (much slower than the shadowfb logic used in the "modesetting" driver. If X rendering is also being done by the GPU then you don't have that problem.

The kernel is in the rolling release part of Fedora anyway.
They would have to patch mesa-9.1 to build against llvm-3.3 so that combination does not make much sense. So they probably either ship mesa-9.1 and patched llvm-3.2, or mesa-9.2 git snapshot and llvm-3.3 svn snapshot.

The latter seems not unlikely to me, as not so many Fedora packages besides Mesa depend on LLVM (opengtl, dragonegg, anything else?).

Everything in Fedora gets 1 major upgrade in that release's lifetime. From kernel to mesa to KDE. So they could ship mesa 9.1 and upgrade to 9.2 upon release. Same with kernel, they'll ship 3.9 and upgrade to 3.10. But not 3.11 (or 4.0 depending on how Linus is feeling)
